Closet bowl ventilator



Dec. 19, 1933. l. BYSTROM CLOSET BOWL VENTILATOR Filed May 19, 1932 I. Byslroin' I I" a Patented Dec. 19, 1933 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to ventilators for closet bowls and the general object is to provide a ventilating means which will be disposed closely adjacent the top of the bowl just below the seat so 5 that a space is provided within which offensive odors may gather and from which they are carried off by a pipe leading to a vent pipe.

A further object is to provide a construction of this character in which a bowl is provided ill with a gasket upon which the seat rests and in which the bowl is further provided with a cast vent opening or pipe to the end that when the seat is being used, a channel may be provided just under the seat cover from which the ventilating pipe leads.

My invention is illustrated in the accompanying drawing, wherein:-

Figure 1 is a top plan view of a bowl constructed in accordance with my invention; 7

Figure 2 is a vertical sectional view on the line 22 of Figure 1.

Referring to the drawing, 10 designates a closet bowl of any usual or suitable construction and illustrated as provided with the usual flushing channel 11 connected at its rear by a duct 12 to the water inlet 13.

As illustrated the top of the bowl is formed with the upwardly extending integral head or flange 14 which is preferably recessed, the recess being dove-tailed in cross section for the reception of a gasket 15 of any suitable material and against which the seat 16 rests, this seat being hinged or otherwise mounted in any suitable manner and the seat being provided with the 35 usual cover.

As illustrated, the upwardly extending flange 15 is formed with an opening 1'7. Rearwardly of this opening the bowl is formed with the extension 18, the water inlet opening 13 being formed in this extension and adapted to be disposed upon this extension is the pipe 19 which, as illustrated, may be disposed in either of two positions extending rearwardly and laterally in one direction or rearwardly and laterally in the other direction on each side of the water supply connection. This construction permits the opening 1'? to be connected up with a vent pipe 20 which is disposed rearward of and to the right of the bowl or rearward of and to the left of the bowl. While I have illustrated the connection to the vent pipe as being formed by a pipe 19,1 do not wish to be limited to this as it is obvious that the bowl itself might be formed to provide a duct communicating with the pipe 19.

It will be seen that with this construction when the bowl is in use, a channel is formed just beneath the seat with which the opening 17 communicates so that the upper portion of the bowl is connected directly with the vent pipe and thus all unpleasant odors are carried off immediately and directly.

It will also be seen that the bowl is not changed in essential respects, that the cost of the bowl is not increased to any particular extent and that the flushing means for the closet need not be changed in any way. Obviously slight modifications may be made to suit the device to diilerent forms of bowls and, therefore, I do not wish to be limited to the details and arrangement of construction except as defined in the appended claims.-

1. A closet bowl having an integral rib formed upon its rim, the rib being narrower than the rim, a seat resting upon said rib, the seat and rib defining a channel extending entirely around the bowl, the rib at one portion of the bowl being cut away to form an opening, a vent pipe and a tubular connection leading from the opening in said, rib to said vent pipe.

2. A closet bowl having an integral rib formed upon its rim, the rib being narrower than the rim, the inner face of the rib being outward of the inner face of the rim, the seat and rib together defining a channel extending entirely around the bowl, the rib at the rear portion of the bowl being cut away to form an opening, a vent pipe, and a tubular connection leading from the opening in said rib to said vent pipe, the connection extending to the top of the rib.
